Not using the powerplant bar

[GAZ_86]

Right i have be searching for about half hour now and cant find the answer,
I remember hearing or reading a thread about the power plant bar pro\'s and con\'s about using it and then gettiing rid of it and just solid mounting the rear diff and rubber mount the gearbox.
 
so should i use it or not?
 
thanks

Yes, use it. It braces the entire drivetrain, as well as supports the gearbox. If you didn\'t use it, you\'d have to fab up mounts for the rear of the gearbox, and the front of the diff, surely, as well as losing some of the stiffness of the car.

I don\'t see why you\'d want to get rid, other than weightm and by the timne you\'d sorted out the mounts and additional bracing, then surely that would be negated?

Hi Gary,
I would say use it if you can,or shorten if if needed.
How is the Starlet coming on?
Ready for an engine yet?

yeah i dont mind putting in the work to make the mounts up, i will be running a fair bit of power so would need to no what would be strongest
 
 
hey carl, yeah it\'s coming along, had a break from it and been working on a couple other projects:yes, but i need to get it off to the cag place to get a full front to back weld in cage then off to paint, will prob be a few month\'s, was wanting to get it done this year but the race season has pretty much finished now so looking to get it done for feb-march time
 
how you been any progress on that beast of a rx3?
you got your matt black rx7 fully run in? i need to get out in that:3gears-rh

You might want to look into what is used to support the gearbox and diff when a V8 conversion is done as the ppf is done away with, there are a couple of alternatives but I would say the best on the market at the moment is made by Justin Samberg.

You could either ship over his mount or make something similar yourself.

Bear in mind that gary is using the FD gearbox too.

I appreciate that but as he\'s said he\'s not against making mounts up. At least it would give him the option of having a ready alternative for the diff so he would only have to fab or modify a mount for the gearbox.  

How come a shorter ppf is needed anyhow, running a swb fd?:xconfused

Gary is building a rotary powered Starlet.
